Start with conditions, not a product
Installation method, flashing, sill condition, frame material, glass package, trim restoration, and solar exposure matter as much as the unit itself.

Waukegan context
Waukegan's oldest housing stock, concentrated in the Near North Historic District that reaches back to the 1840s, was largely built before modern window units existed, and later postwar and contemporary construction added its own range of opening sizes and frame materials. Add lakefront wind exposure off Lake Michigan and the freeze-thaw cycle that comes with it, and opening condition, flashing, and frame material matter as much in Waukegan as the glass package itself.
